.SH Synopsis
   bitset operator<<( std::size_t pos ) const; \fB(1)\fP (noexcept since C++11)
                                                   (constexpr since C++23)
   bitset& operator<<=( std::size_t pos );     \fB(2)\fP (noexcept since C++11)
                                                   (constexpr since C++23)
   bitset operator>>( std::size_t pos ) const; \fB(3)\fP (noexcept since C++11)
                                                   (constexpr since C++23)
   bitset& operator>>=( std::size_t pos );     \fB(4)\fP (noexcept since C++11)
                                                   (constexpr since C++23)

   Performs binary shift left (towards higher index positions) and binary shift right
   (towards lower index positions). Zeroes are shifted in, and bits that would go to an
   index out of range are dropped (ignored).

   1,2) Performs binary shift left. The \fB(2)\fP version is destructive, i.e. performs the
   shift to the current object.
   3,4) Performs binary shift right. The \fB(4)\fP version is destructive, i.e. performs the
   shift to the current object.

.SH Parameters

   pos - number of positions to shift the bits

.SH Return value

   1,3) New bitset object containing the shifted bits.
   2,4) *this

.SH Example


// Run this code

 #include <bitset>
 #include <iostream>

 int main()
 {
     std::bitset<8> b{0b01110010};
     std::cout << b << " (initial value)\\n";

     for (; b.any(); b >>= 1)
     {
         while (!b.test(0))
             b >>= 1;
         std::cout << b << '\\n';
     }

     std::cout << b << " (final value)\\n";
 }

.SH Output:

 01110010 (initial value)
 00111001
 00000111
 00000011
 00000001
 00000000 (final value)
